IMPROVEMENT IN NECK-YOKE PASTENING.

'TO ALL WHOM I'l MAY CONCERN:

Be it known that'I, HENRY J. LAMM, ofthe city ot Richmond, and State of Indiana, have invented a new and useful Improvement in Fast-enings fornNeck-Yokes of Carriages, Ste.; and I do hereby declare that the followingis a full, clear, and exact description of the same, reference being hadto the accompanying drawings,` .r making a part of this specification, in which- A y r Figure 1 is a view oi' the neck-yoke as connected with the tongue or pole ofthe carriage.`

Figure 2 represents the connecting-shank, and

Figure 3 asection ofthe yoke.

The same letters in the different figures relate to corresponding parts of the invention.

The nature of my invention consists in an attachment or fastening for the ncck-ybkes of carriages, Sec., byi the use of a metallic connecting-shank, in such a manner as to give the necessary lateral and horizontal motion obtained by the leather, as in ordinary use. Great advantages in economy anddurability are thus gained. y

To enable others skilled in the art to make and use my invention',` I will proceed todescribe it with refcrence to the drawings.

4 A represents a socket on the end of the tongue or pole G of the carriage. B represents the neck-yoke, and C the connecting-shank. The socket A is `solid to a distance from its terminating end about equal tothe length of the end F ot' the shank, excepting the orifice of proper size to closely admit the said end F, the remaining portion of the socket being made suitable as a. thimble for the end of the tongue. Jrepresents` l a shoulder on the shank, regulating the depth to which `the end F is inserted. I represents a rubber collar or hand on the it.se.ted end of the shank, for the purpose of obviating any rattlii'g of the said devices. 6 is a hollow screw, formed of the endsof the band E, brought together, and 4thus making said screw of discon` ncctcd halves. A suitable recess is formed within the screw b, and near the yoke, into which the head e is admitted as the end of the shank is' inserted by forcing apart the halves composing the screw. i The nut D is then screwed up, as shown in fig. 1,'thus securing the parts and forming a swivel connection admitting of `a horizontal turning of theyokc. The manner of connecting the end F, by inserting the same in the socket A, admit-s of the necessary lateral motion ofthe devices.

` Having thus fully described my said invention, what I claim, and desire to secure by Letters Patent, isv 1. I claim the combination of the socket A, shank C, and neck-yoke B, when arranged, to admit of the` swivel action at each end of the shank, substantially as described and for thepurpose specified. i 2. I claim the open screw b, 'the end cl, having a head, e, andthe nut D, for obtaining a swivel-joint, when used in combination with the yoke B and shank C, substantially as sot forth, and for the purpose described. 3. I claim, in combination with the socket A and shank C, the rubber band I,substantially as set forth,

i and "for the purpose described.
